In vivo (Latin for “within the living”) is experimentation using a whole, living organism as opposed to a partial or dead organism. Animal testing and clinical trials are two forms of in vivo research. On average around 300,000 animals per year are used in experimentation, testing and teaching in New Zealand – from cats and dogs to rabbits, deer, mice, rats, fish, birds, pigs, cows and guinea pigs. This particular former testing facility has been irresponsibly left to the ravages of time and vandalism, a haunting reminder of what we commit in the name of science.
